AT&T Plans to Offer
Free In-Network Calls
To Wireless Customers

Newly merged AT&T Inc. plans to allow its wireless subscribers to make free calls to landline, Internet and wireless phone numbers operated by the company.

Under a plan available Sunday, customers of the former Cingular Wireless, which AT&T has rebranded with its own moniker, will be able to dial other AT&T domestic numbers without using minutes. AT&T hopes the plan will appeal to small-business customers.
